I haven't been around btc for a while, can someone tell is there a particular reason why we are going up?
Something happened?
Please, refrain yourself from telling that demand is bigger than supply

I'm interested only if there are some significant news. Thank you friends!

There's about a million reasons coming together at once, it's the perfect storm.
The New World Order has decided to front run Bitcoin to make money themselves instead of try and ban it, so they've legally made it a currency in the EU, placed it on the cover of The Economist and Bloomberg in the same month, and now said it's going to be a world reserve currency:

China might be on the verge of a serious economic implosion that we highly underestimate:

Then the fact that TONS of people were sitting out of Bitcoin waiting for "the bottom". Now that they know the bottom is already in, everyone is having to buy back when it started to go up.
You also have the fact that whales have planned all along to accumulate, wait till 70% of coins are mined, then start to pump.
